Regularly, I'd walk in a park near my workplace to work out problems and I began too often to play games and tricks with the magpies (another type of Corvid like the crow). I'd do things like throwing twigs on either side of them to see how they would react (no magpies ever injured!). After a while I'm certain the magpies had a particular warning call any one would call out when I arrived in the park that would set them all of making that cawking sound until I left. After a while I needed to avoid the park for a bit and I think I was forgiven when I slowly started integrating myself in by leaving bits of food like nuts. I was amazed too at how observant they were, keeping a different distance if they noticed I had am umbrella or something in my hand or if I was walking funny. The magpie is the only bird to pass the mirror test: http://en.wikipedia.org/wiki/Eurasian_magpie#Intelligence http://en.wikipedia.org/wiki/Eurasian_magpie#Intelligence
